There are times that the filament is skinned due to a clog, incorrect hot end temperature or a loose idler tensioner. It can result in no filament extruding from the printer.
There are several ways you can fix this problem.
- Tweak the idler tension’s settings: Loosen up the idler tension and load the filament. Tighten the idler until the filament stops slipping.
- Remove the filament: Remove the filament and cut off the area that is marked with signs of slipping. Help feed the filament into the printer by applying a gentle pressure to get it through the system.
- Make sure you have the right hotend temperature: It could be that you have the wrong temperature if the problem arises just after inserting a new filament.
